Yesterday, I saw one little people.................. Are you talking about me ? My name is yili, is your earth fairy.your job is about earth. Today, we talk about volcano！ Look there! Volcano is the high temperature deep underground magma and its associated gases , debris from the crust formed ejected, the geological structure has a special form. Volcano can be divided extinct and active volcanoes . A period of time, there was no active volcano eruptions, called sleeping volcano ( dormant volcano ). There is also a mud volcano , which, strictly speaking, does not belong in science volcano, but many public also see it as a type of volcano. Volcanic eruption is a very serious natural disaster , it is often accompanied by earthquakes . Therefore volcanic eruption on human harm, but it also brings some benefits. For example: You can promote gems formed; expand the land area ( the Hawaiian Islands is formed by a volcanic eruption); as a tourist attraction visits, promote tourism, such as Japan's Mount Fuji . ______________________________________________________Lily Plate tectonics advocates plate movement is due to the Earth's interior asthenosphere of convection caused. When the plates push each other, while the higher density will drop to the bottom of the other side, called subduction, and subduction occurred strip area called the government thrust belt or polymeric tectonic plates. The ground temperature will melt the plate subduction, magma. With buoyant magma rises slowly, finally gathering together as magma chamber is at the bottom of volcanic magma storage place. When the gas pressure in the magma accumulated to a degree, the volcano erupted. For example: Central Pacific volcanic region, mostly for such volcanoes. Some volcanoes distributed in the rifting of the junction plate, strip area is two plates separated. In this area, the high temperature of mantle material rises, forming undersea volcanic mountain range, known as mid-ocean ridges.

Affected volcanogenic volcano around the world mostly in the tectonic plates, but there are still some exceptions (hot spots). The main volcanic zone include: Ring of Fire (also known as the Ring of Fire): From South America West Coast, the Pacific coast of the Andes , through Central America , Mexico , the US West Coast, Canada to Alaska after, along the Aleutian Islands and the Kamchatka Peninsula to the Pacific West Bank The festoon islands , including the Kuril Islands , Japan , the Ryukyu Islands , Taiwan and its affiliated islands, the Philippine Islands , and then connect Indonesia , Papua New Guinea , Solomon Islands , until New Zealand . The number of the volcanic zone of the volcano about 75% of the world's [2] , and the activities are quite frequent. Mid-ocean ridge volcanic belt include: the Pacific , Atlantic and Indian Ocean, the three oceans of mid-ocean ridges, the total length of about 80,000 kilometers, about a W-shaped distribution. But the mid-ocean ridge volcanoes are not evenly distributed, focusing on the mid-Atlantic ridge, there are more than 60 seats. Pacific and Indian Ocean Ridge volcano is relatively small. Mid-ocean ridge volcanic seafloor volcanoes mainly, but also a small part of the volcanic island (example: Seychelles , Iceland ).
